Paint images using famous artistic styles in seconds (or less!)

quickpaint using pre-trained styles (models) or trainstyle a new model on a new style

a TensorFlow implementation for feed forward CNN fast neural style transfer, based on [1-3].

works with different versions of pre-trained TF models, many pre-trained models included (more to come)

styles	outputs	outputs	styles
rain princess			the shipwreck of the minotaur
wave			mosaic
the scream			composition vii
la muse			cubist
udnie			feathers

GUI:

Command line:

python quickpaint.py -i [ input (content) ] -o [ output (stylized content) ] -m [ model (style) ] -ma [ mask ] -bl [ blend ]

Example: python quickpaint.py -i inputs/stanford.jpg -o outputs/stanford_cubist.jpg -m pre-trained_models/cubist.model -ma 1 -bl 0.05

required arguments:
-i, --input dir or file to transform (content)
-o, --output destination (dir or file) of transformed input (stylized content)
-m, --model path to load model (.ckpt or .model/.meta) from

optional arguments:
-h, --help show this help message and exit
-d, --device device to perform compute on (default: /gpu:0)
-b, --batch-size batch size for feed-forwarding (default: 4)
-a, --model-arch model architecture if models in form (.model) are used, (default: pre-trained_models/model.meta)
-ma, --mask create binary mask from input (@ 1% of max) and mask output (default: 0 -> no masking)
-bl, --blend multiply the original image with the output using a weighting (factor) -- to preserve original colors / contrast (default: 0 -> no blending)

Command line:

python trainstyle.py -s [ style ] -c [ checkpoint dir ] -o [ output test image ] -i [ checkpoint iterations ] -t [ training set path ] -od [ output test dir ] -cw [ content weight ] -tv [ tv weight ] -sw [ style weight ] - b [ batch size ] -l [ learning rate ] -n [ network path ]

Example: python trainstyle.py -s styles/the_scream.jpg -c checkpoint -o stanford.jpg -od test -cw 1.5e1 -i 1000 -b 20

required arguments:
-c, --checkpoint-dir dir to save checkpoint in
-s, --style desired style image path

optional arguments:
-h, --help show this help message and exit
-t, --train-path path to training images folder
-o, --output output test image at every checkpoint path
-od, --output-dir output test images dir
-e, --epochs # of epochs
-b, --batch-size batch size
-i, --checkpoint-iterations checkpoint frequency
-n, --net-path path to VGG19 network (default data/imagenet-vgg-verydeep-19.mat) -cw, --content-weight content weight (default 7.5)
-sw, --style-weight style weight (default 100.0)
-tw, --tv-weight total variation regularization weight (default 200.0)
-l, --learning-rate learning rate (default 0.001)
